MatD - Matlab external interface bindings for D

[eles]

Hi,

 I am interested in using the MatD and mex files in D. Also, if
possible, to contribute.

 For the time being, I see that you are distributing a set of
win32 .lib with MatD. I tried to compile the mex examples you
provided in Linux 64 bit, but dmd failed to link, I think it is
because there is a 32 bit compiler (and the Matlab libmex.so
librariest ec. are 64 bit).

 Now, coming back to the Win32 environment:

 I encounter the following problem.

 On the one hand, when compiling/linking against the libmex.lib and
libmx.lib files that you provided, a (correct) .dll file (or
a .mexw32 file) is generated, along with two other files called
arrayProduct.map and arrayProduct.obj. This is just perfect, the .DLL
works and is recognized by Matlab (win32 bit) as a MEX file.

 On the other hand, when compiling/linking against the .lib files
that come with Matlab (in C:\Matlab\extern\lib\win32\lcc or C:\Matlab
\extern\lib\win32\microsoft folders), only the arrayProduct.map and
arrayProduct.obj are created. Where is the .DLL file? Why dmd (2.048)
does not generate a .DLL file in these cases?

 Finally, when compiling/linking against the 3rd set of .lib files
that come with Matlab, namely those in C:\Matlab\extern\lib
\win32\watcom, a strange thing happens: all three files
arrayProduct.obj, arrayProduct.map and arrayProduct.DLL are created,
but the compilation presumably fails since it displays:

D:\testare_mex_d>dmd arrayProduct.d dllmain.d dlldef.def c:\matlab
\extern\lib\wi
n32\watcom\libmex.lib c:\matlab\extern\lib\win32\watcom\libmx.lib

 Why this? Are the .lib files that you are distributing along with
MatD special in any way?

 Thanks,
